WELDER CONTROLS:

FUNCTION/OPERATION

PORTABLE FIELD CONTROL CONNECTION

A “Portable Field Control” complete with 25’ leads is shipped with each SAM welder.

A “Portable Field Control” is not required for proper operation of the SAM welder when connected to an LN-8, LN-9, NA-3, NA-5, LT-7, or LT-56 wire feeder. With other wire feeders and when stick electrode weld- ing, the “Portable Field Control” must be installed or the SAM cannot produce its full open circuit voltage.

When installed the “Portable Field Control” is a fine voltage adjustment when using the SAM as a constant voltage power source. It is a fine current adjustment when using the SAM as a variable voltage power source.

The “Portable Field Control” can be mounted on the SAM or wherever convenient for the welding operation. When using an LN-4, LN-5, LN-6 or LN-7 wire feeder, the control should normally be mounted on the wire feeder. Specific mounting instructions are given below.

After mounting, connect the “Portable Field Control” leads to #75 and #76 on the SAM terminal strip locat- ed behind the lower cover panel directly below the con- trol panel on the SAM400 or behind the right front hinged door on the SAM650. Connect the green lead of the “Portable Field Control” to the grounding stud

marked with the symbol located near the terminal strips.

MOUNTING ON LN-4 (Discontinued)

1.Place the “Portable Field Control” on the vertical front panel of the LN-4 on the wire reel side (next to the rheostat panel) and mark the location of the mounting slots.

2.Drill two holes in the panel and mount the control using #10 sheet metal screws.

3.Route the leads with the LN-4 control cable back to the power source.

MOUNTING ON LN-5 OR LN-6 (Discontinued)

1.Remove the knob from the upper rheostat on the wire feeder control panel.

2.Be sure the appropriate wire feeder nameplate - “Constant Voltage” or “ Variable Voltage “ - is in

place.

3.Remove the two screws on the top end of the wire feeder nameplate.

4.Position the “Portable Field Control” mounting slots over these holes and replace the screws.

5.Route the leads with the LN-5 or LN-6 control cable back to the power source.

MOUNTING ON LN-7

1.Remove the top screws on the side of the LN-7 con- trol box cover. (This is the left side when facing the nameplate).

2.Position the “Portable Field Control” on the side of the control box with the mounting slots over these holes and replace the screws.

3.Route the leads with the LN-7 control cable back to the power source.

OUTPUT STUDS

With the Engine OFF connect the work cable to the “To Work” stud.

A.For Stick Electrode Welding

1.Connect the electrode cable to the “Stick” stud and the work cable to the “To Work” stud. Connect the “TAP” lead in the SAM650 to the appropriate stud to adjust current and the arc characteristics as described under “Current and Voltage Controls.”

2.Install the “Portable Field Control”.

B.Automatic or Semiautomatic Welding

For all automatic welding processes, connect the welding power cable from the wire feeder to the “Connect to Auto. Equipment” stud. Connect the “TAP” lead in the SAM650 to the appropriate stud to adjust current and the arc characteristics as described under “Current and Voltage Controls.”

1.LN-7, LN-8, LN-9, NA-3, NA-5, LT-7 and LT- 56 Wire Feeders.

a.Make the connections exactly as speci- fied on the connection wiring diagram included in the wire feeder Instruction Manual.

b.Install the “Portable Field Control” when using an LN-7.

SAM650, SAM400 specifications

Lincoln Electric has long been synonymous with welding excellence, and its SAM series of advanced welding machines, including the SAM400 and SAM650, epitomizes this commitment to quality and innovation. These models are designed to meet the demands of diverse industrial applications while ensuring ease of use, efficiency, and precision.

The SAM400 is a robust multiprocess welding system that supports MIG, TIG, Stick, and Flux-Cored welding techniques. It features a powerful 400 Amp output, suitable for heavy-duty applications and capable of handling materials such as steel, stainless steel, and aluminum. The machine incorporates advanced inverter technology, resulting in a compact design that significantly reduces the weight while enhancing portability. Furthermore, the SAM400 includes intuitive digital controls, allowing operators to easily adjust settings for optimal performance. Its PAS (Power Adapter System) compatibility enables users to seamlessly integrate different power sources, greatly enhancing its versatility.

On the other hand, the SAM650 takes it a step further, boasting a maximum output of 650 Amps. This model is particularly favored in industries requiring high deposition rates, such as shipbuilding and heavy fabrication. Like the SAM400, the SAM650 features multiprocess capabilities but adds enhanced control mechanisms, such as advanced waveform technology, which allows for better arc stability and reduced spatter. This ensures cleaner welds and, ultimately, a superior finish. Additionally, the SAM650 is equipped with Lincoln Electric's proprietary welding technology, including the Arc Control and Hot Start features that enhance user experience by providing smoother starts and consistent performance, even in challenging conditions.

Both machines come with integrated wire feeders that allow for easy adjustments and quick material changes, offering increased productivity on the job site. Their rugged design and durable construction ensure long-lasting performance, even in the harshest environments.

In conclusion, the Lincoln Electric SAM400 and SAM650 welding systems are trailblazers in the field of welding technology. With their powerful output, advanced features, and user-friendly interfaces, these machines cater to the needs of professionals looking for reliability and efficiency in their welding applications. Whether for small shops or large-scale industrial operations, the SAM400 and SAM650 deliver the performance and versatility that fabricators and welders depend on.
